The Bear River Massacre, or the Battle of Bear River or Massacre at Boa Ogoi, took place in present-day Idaho on January 29, 1863. After years of skirmishes and food raids on farms and ranches, the United States Army attacked a Shoshone encampment, gathered at the confluence of the Bear River and Beaver Creek in what was then southeastern Washington Territory. The site is located just north of the present-day city of Preston in Franklin County, Idaho. Colonel Patrick Edward Connor led a detachment of California Volunteers as part of the Bear River Expedition against Shoshone Chief Bear Hunter. Hundreds of Shoshone men, women and children were killed near their lodges, while only two dozen soldiers died. The number of Shoshone victims reported by local settlers was higher than that reported by soldiers. Of the six major Indian massacres in the Far West, from Bear River in 1863 to Wounded Knee in 1890, the Bear River affair resulted in the most victims, an event which today deserves greater attention than the mere sign presently at the site.
